Background:The International Linear Collider is a proposed electron-positron collider. The Reference Design Report provides the first detailed technical snapshot of the ILC and includes a preliminary value estimate to obtain guidance for optimisation of both the design process and R&D during the engineering phase. More information about the ILC is available at www.linearcollider.org.

A cryostat for ILC R&D studies. The superconducting cavities for the ILC will sit inside cryostats - vessels surrounded by thermal shields and an outer tank - to maintain their near absolute zero temperatures.
